The second terminal control unit 44 terminates the setting program upon receiving a normal reception response from the management server MS.

(Operation when connected)
FIG. 8 is a schematic diagram of the processing of the system 1 when the first terminal RT1 and the surveying instrument TS are connected.

When the surveying instrument TS is connected to the first terminal RT1 via the respective external interfaces 14b and 35 using a connection cable, the process starts. , and the surveying instrument TS responds to the reception in step S202.

Then, when the connection between the first terminal RT1 and the surveying instrument TS is established, the first terminal RT1 reads the unique information of the surveying instrument TS from the surveying instrument TS in step S203, and reads the unique information in step S204. get.

Next, in step S205, the first terminal control unit 32 of the first terminal RT1 transmits an operation execution program in the form of a self-extracting file for causing the surveying instrument TS to execute a predetermined operation. According to the operation execution program, when the power of the surveying instrument TS is turned on, the surveying instrument TS sends its own position information to the first terminal at regular intervals such as once an hour or at least once a day. Determining whether a predetermined time has passed from the time when data was exchanged with the management server MS via the first operation execution program for executing the operation of automatic transmission to RT1 and the first terminal RT1, It includes a second operation execution program for locking the function of the surveying instrument TS.

In step S206, when the surveying instrument TS responds to receive the operation execution program, in step S207, if the operation execution program is not installed in the surveying instrument TS, the decompression program is started, and the operation execution program is installed in the surveying instrument TS in step S207. Install it in TS and run the operation execution program. On the other hand, if the action execution program has already been installed, the installed action execution program is executed without being installed.

On the other hand, in step S208, the first terminal RT1 transmits the unique information of the surveying instrument TS received in S203 to the management server MS, and in step S209, the management server MS responds to the reception.

When the management server MS receives the unique information of the surveying instrument TS, in step S210, the server control unit 52 extracts the management number from the correspondence table between the unique information of the surveying instrument TS and the management number stored in the database 54. The search is performed, the management number given to the surveying instrument TS is associated with the unique information of the surveying instrument TS, and the process ends.

(Processing when first action is executed)
FIG. 9 is a schematic diagram of the operation of the system 1 when the surveying instrument TS executes the first operation execution program. When the power of the surveying instrument TS is turned on, the surveying instrument TS performs the following operations at regular intervals, such as once an hour or at least once a day, according to the first operation execution program.

When the process starts, in step S301, the surveying instrument TS transmits data to the first terminal RT1 by the operation according to the operation execution program. That is, the location information of the device itself and the unique information are associated with each other and transmitted to the first terminal RT1.

The first terminal RT1 transmits the data received from the surveying instrument TS to the management server MS in step S302.

Next, in step S303, the management server MS makes a reception response, and in step S304, the first terminal RT1 returns the reception response to the surveying instrument TS. The server control unit 52 of the management server MS stores the received data in the database 53 in association with the management number of the surveying instrument TS.

Next, in step S305, the setting condition reading unit 55 reads from the database 53 the usable range that is stored in association with the management number of the surveying instrument TS. judge. If the determination condition is not satisfied (No), the management server MS makes a normal response in step S306, the first terminal RT1 returns this to the surveying instrument TS in step S307, and ends the process.

On the other hand, if the predetermined condition is satisfied, the action executing section 57 executes the action specified in step S308.

In step S308, if the specified operation is specifically an operation to be executed by the surveying instrument TS, such as "display a warning on the surveying instrument" or "lock the surveying instrument (stop functioning)", At step S310, the operation execution unit 57 transmits a designated operation execution command to the first terminal RT1, and at step S311, the first terminal RT1 transmits this to the surveying instrument TS.

Upon receiving the command, the surveying instrument TS transmits a reception response to the first terminal RT1 in step S312, and the first terminal RT1 transmits this to the management server MS in step S313. Next, the surveying instrument TS executes the designated operation in step S314.

In each step of data transmission/reception and reception response, the control section 17 of the surveying instrument TS stores the time in the memory.

(Processing when executing the second operation)
FIG. 10 is a flow chart of processing of the surveying instrument TS when the second action execution program is executed. The surveying instrument TS always performs the processing of FIG. 10 by executing the second operation execution program.

When the process starts, in step S401, the control unit 17 of the surveying instrument TS receives the time at which the previous data reception response was received from the management server MS in step S304, the time at which the previous normal response was received from the management server MS in step S307, and At least one time selected from the time when the specified operation command was received from the management server MS last time in step S311 (these operations are hereinafter collectively referred to as "previous communication") is compared with the current time. to determine whether or not a certain period of time has passed since the previous exchange.

If the predetermined period of time has not elapsed (No), the control unit 17 determines that communication with the management server MS is normally performed, shifts the process to step S402, and executes the operation by the first operation execution program. and return to step S401.

If the predetermined time has passed (Yes), the control unit 17 determines that the predetermined time has passed while the communication with the management server MS is disconnected and the surveying instrument TS is not managed normally. In step S403, a warning is displayed on the display unit 16, and in step S404, the function is locked, and the process ends.

A usage example of the system 1 according to the present embodiment is shown. An example of the case where the manager who owns the surveying instrument TS uses this system because he does not want the surveying instrument TS to be taken out of the vicinity of the site will be described.
(1) The administrator opens the Web page 60 on the second terminal RT2, and reads "Usable range: 100m radius from site center", "Judgment: When out of range", "Action: Display warning on surveying instrument TS and Lock the function and notify the administrator by mail” is set and saved, and the web page 60 is closed.
(2) The user connects the first terminal RT1 and the surveying instrument TS using a connection cable. As a result, when the surveying instrument TS does not communicate with the first operation execution program for transmitting the position information to the first terminal RT1 every hour, and the surveying instrument TS and the management server MS for a certain period of time. A second operation execution program for locking the function of the surveying instrument TS is installed in the surveying instrument TS.
(3) The surveying instrument TS transmits its own location information to the management server MS via the first terminal RT1 every hour. When the management server MS receives the position information, it compares the position of the surveying instrument TS with the usable range specified in (1) based on the GNSS coordinates. When the surveying instrument TS is being used within the range, the management server MS transmits a normal response to the surveying instrument TS via the first terminal RT1, and the user can normally use the surveying instrument TS.
(4) On the other hand, when detecting usage outside the range, the management server MS issues a command to display a warning on the surveying instrument TS and lock the function based on the operation set in (1). The data is transmitted to the surveying instrument TS via the first terminal RT1, and the administrator is notified by mail that the surveying instrument TS is being used out of range. Upon receiving the command from the management server MS, the surveying instrument TS displays a warning on the display unit 16, and then stops operations other than turning off the power (locks functions).
(5) When a certain period of time has elapsed since the previous communication between the surveying instrument TS and the management server MS, the surveying instrument TS displays a warning on the display unit 16 and stops operations other than turning off the power (locks the function).

In the system 1, when the first terminal RT1 is connected to the surveying instrument TS, as a predetermined operation, for example, the surveying instrument TS outputs predetermined data (positional information) to the first terminal RT1. is installed in the surveying instrument TS, the first terminal RT1 transmits data input from the surveying instrument TS to the management server MS, and transmits data received from the management server MS to the surveying instrument TS. It is configured to output to the machine TS.

Therefore, even if the surveying instrument TS itself does not have a communication unit for communication via the communication network to which the management server MS is connected, the surveying instrument TS can communicate with the management server MS via the first terminal RT1. It is possible to exchange data with As a result, the surveying instrument TS can be managed by the management server through the communication network so that it is not used illegally or in an inappropriate state, like a state-of-the-art surveying instrument having a communication unit. .

Further, in the system 1, when the surveying instrument TS is connected to the first terminal RT1 and the surveying instrument TS is connected, if the surveying instrument TS does not communicate with the management server MS for a certain period of time, the operation of the surveying instrument TS is performed as a predetermined operation. A first terminal between the surveying instrument TS and the management server MS based on the execution of the first operation executing program, installed in the surveying instrument TS, for executing the operation of stopping the function. The function of the surveying instrument TS is stopped when a certain period of time has elapsed since the previous exchange via RT1.

Therefore, even when the connection between the surveying instrument TS and the first terminal RT1 is released, it is prevented from being used in a state beyond the control of the management server MS as in the past against the intention of the administrator. can do. In addition, even if the surveying instrument TS is separated from the first terminal RT1 and an attempt is made to use the surveying instrument TS illegally or inappropriately, the surveying instrument TS cannot be used. It can be prevented from being used illegally or inappropriately.

In addition, in the system 1, unique information of the surveying instrument TS is registered in advance, linked with a management number used when the administrator makes settings on the web page 60, and is transmitted from the surveying instrument TS to the first terminal RT1. The data to be obtained is associated with the unique information of the surveying instrument TS and transmitted to the management server.

If the management server MS manages all the surveying instruments connected via the communication network N in the same way, it is not necessary to specify the surveying instrument TS. However, as described above, by associating the unique information of the surveying instrument TS with the management number, the management server MS can specify the specific surveying instrument TS. In addition, since the administrator who performs management settings on the web page 60 can recognize the surveying instrument TS only by the management number, it is possible to reduce the administrator's labor.

Further, in the system 1, when installing the operation execution program in the surveying instrument TS, it is installed only when it is not already installed, and when it is already installed, the operation execution program is executed.

Therefore, once the first terminal RT1 and the surveying instrument TS are connected, there is no need to install the same operation execution program again when connecting the second time or later, and the processing time can be shortened. . When the connection is made for the second time or later, the operation execution program is executed. Therefore, even if the connection between the first terminal RT1 and the surveying instrument TS is temporarily separated, the function of the surveying instrument TS is maintained. If the connection is reconnected before the fixed period of time has elapsed, the management server can continue to perform management.

As described at the beginning of the embodiment, in the above example, the position information of the surveying instrument is transmitted to the management server at regular time intervals, and the management server causes the surveying instrument to deviate from the preset range. This is an example applied to a communication management system in which it is determined whether or not the surveying instrument is active, and the function of the surveying instrument is locked based on the result of the determination. For example, as a communication management system to which this embodiment can be applied, the following can also be mentioned.

(a) As described in Patent Document 2, the surveying instrument is provided with a clock for acquiring the current time, and the surveying instrument acquires the operation start time and the operation end time of itself as a first predetermined operation. The time data is sent to the management server, and the management server judges the usable time of the surveying instrument based on the received time data. Communication management system for surveying instruments to be managed.
(b) equipping a surveying instrument with a temperature sensor as described in Patent Document 3, and transmitting temperature information of the surveying instrument to a management server at regular intervals as a first predetermined operation; Communication in which the management server judges whether or not the surveying instrument deviates from the preset temperature range based on the received temperature data, and manages such as locking the surveying instrument functions based on the judgment result. management system.
(c) Communication management in which the surveying instrument transmits survey data to the management server as a first predetermined operation for each survey or at regular intervals, and the management server analyzes or saves the survey data. system.
(d) A communication management system in which the surveying instrument transmits machine logs and error information to the management server at regular time intervals or in the event of an error as a first predetermined operation, and maintenance management is performed based on the data received by the management server. .

(Second embodiment)

The system 1A has the same mechanical configuration as the system 1, but when the first terminal RT1A is connected to the surveying instrument TS via the terminal external interface 35b, the operation execution program is transmitted to the surveying instrument TS. , in that the operation execution program is executed by the first terminal RT1A itself instead of being installed in the surveying instrument.

FIG. 11 is a schematic diagram of processing of the system 1A when the first terminal RT1A and the surveying instrument TS are connected. An example of communication management similar to that of the first embodiment will be described below.

When the first terminal RT1A and the surveying instrument TS are connected and the process starts, in steps S501 to S504, similar to steps S201 to S204, confirmation of connection and acquisition of specific information are performed.

Then, in step S505, the first terminal control unit of the first terminal RT1A reads and executes the operation execution program stored in the first terminal storage unit.

The operation execution program is a normal execution program, and when the power of the surveying instrument TS is turned on, the first terminal RT1A executes the surveying at regular intervals such as once an hour or at least once a day. The first operation execution program for referring to the position information of the surveying instrument TS and the first terminal RT1A determine whether a predetermined period of time has elapsed from the time when data was exchanged with the management server MS. A second action execution program for locking the function is included. The operation during execution of the action execution program will be described later.

Next, in steps S506 and S507, the first terminal RT1A transmits the acquired unique information of the surveying instrument TS to the management server MS and receives a response to the reception, in the same manner as the first terminal RT1. After that, in step S508, the management server MS associates the unique information with the management number in the same manner as in step S210.

FIG. 12 is a diagram showing an outline of processing when the first terminal RT1A executes the first action execution program.

When the process starts, the first terminal RT1A refers to the surveying instrument TS in step S601, and acquires data (positional information) from the surveying instrument TS in step S602.

Next, the first terminal RT1A transmits the acquired data to the management server MS in step S603, and the management server MS makes a reception response in step S604.
Since subsequent processing is the same as in the case of system 1, description thereof is omitted.

In the system 1A, the first terminal RT1A executes the operation execution program instead of installing the operation execution program in the surveying instrument TS to obtain the data of the surveying instrument. The processing is the same for the second action execution program.

Thus, even if the operation execution program is not installed in the surveying instrument TS but is executed by the first remote terminal RT1A, as in the system 1, the surveying instrument TS itself and the management server MS The surveying instrument TS can exchange data with the management server MS via the first terminal RT1 even if it does not have a communication unit for communication via the connected communication network. As a result, the surveying instrument TS can be managed by the management server through the communication network so that it is not used illegally or in an inappropriate state, like a state-of-the-art surveying instrument having a communication unit. .

In the system 1A, unlike the system 1, when the connection between the surveying instrument TS and the first terminal RT1A is disconnected, there is no communication between the management server MS and the first terminal RT1A for a certain period of time. Even in this case, the function of the surveying instrument TS cannot be locked. Therefore, as in the case of the system 1, only the second operation execution program may be configured to be installed in the surveying instrument TS at the time of connection as a program executed by the surveying instrument TS.

(Third Embodiment) FIG. 13 is a diagram showing the overall configuration of a surveying instrument management system 1B according to a third embodiment. The system 1B includes a management server MS having the same mechanical configuration as the system 1, a first terminal RT1B, a second terminal RT2, and a surveying instrument TS. 14b and 35b in that a connection adapter (hereinafter simply referred to as "adapter") 70 is further provided. Also, the first terminal RT1B according to the third embodiment does not have an operation execution program.

As shown in FIG. 14, the adapter 70 includes an adapter control section 71, an adapter output section 72a, an adapter external interface 72b, and an adapter input section 72c.

The adapter control section 71 is a control unit including a CPU and memory (ROM, RAM, etc.). The memory of the adapter control unit 71 stores an operation execution program for causing the surveying instrument TS to execute a predetermined operation, as in the first embodiment.

The adapter output section 72a, the adapter external interface 72b, and the adapter input section 72c enable data transmission/reception without going through the communication network N. FIG. The adapter external interface 72b is a USB connector, and one is provided on the input side and the other on the output side. By connecting the adapter external interface 72b to the external interface 14b of the surveying instrument TS and the external interface 35b of the first terminal RT1, communication between the surveying instrument TS and the first terminal RT1 is enabled.

When the surveying instrument TS and the first terminal are connected via the adapter 70, the adapter control unit 71, like the first terminal control unit 32 in the system 1, extracts an operation execution program in a self-extracting format. It transmits to the surveying instrument TS and installs the operation execution program in the surveying instrument TS.

Therefore, the adapter control section 71 in the system 1B plays the same role as the terminal control section 32 in the system 1B.

As described above, the adapter 70 having the adapter control unit 71 and capable of connecting the surveying instrument TS and the first terminal RT1B is further provided. When the first terminal RT1 is not equipped with a special program and the surveying instrument TS is not equipped with a communication function via the communication network N, because the operation execution program is installed in the surveying instrument TS when the is connected to However, the surveying instrument TS can be managed by the management server MS.

Note that the adapter control unit 71 is not provided with an operation execution program for causing the surveying instrument TS to execute a predetermined operation, but the first terminal RT1 B can execute a predetermined operation like the first terminal RT1A related to the system 1A. An operation execution program for executing the operation of (1) may be provided, and a predetermined operation may be executed when the surveying instrument TS and the first terminal RT are connected.
